Firefighters battled a blaze at an abandoned building at 112 NW 7 Saturday morning that caused heavy damage to the structure.

Oklahoma City Fire Department Battalion Chief Tommy Iago said crews were called to the abandoned building about 1 a.m. Saturday morning. When firefighters arrived they could see heavy flames on the first and second floors. The fire in the three-story building was stubborn.

“We thought we had it knocked down but it extended up to the walls and was coming out of the second and third floor window,” Iago said.

Iago said the floors collapsed during the blaze. One firefighter was hospitalized with unspecified medical issues, Iago said. Iago said he remained in the hospital on Saturday.

According to property records, the 18,000-square-foot building was built in 1911. It was sold in 2008 for $650,000.

Witness Jeff Halpin said the fire is intense and is “filling up MidTown with smoke.”
